Glufosinate, nicosulfuron and combinations in the performance of maize hybrids with the pat gene

Combinations of glufosinate with nicosulfuron, among other post-emergent herbicides, are promising for weed controlin maize. However, some these herbicides can cause injury and have undesirable effects on the maize, so it is necessaryto investigate their selectivity cultivation. The aim this study was to evaluate glufosinate, nicosulfuron andcombinations, by analysing agronomic performance crop application in maize hybrids pat gene.Two experiments were conducted state Paraná, Brazil, during 2019/2020 season, a 2 x 8 (exp. I) 4 II)factorial scheme. Two used (FS505 PWU FS715 PWU), eight levels factor herbicide experiment I(glufosinate, halosulfuron combination halosulfuron, atrazine, tembotrione or mesotrione, inaddition control no application) four II (nicosulfuron two formulations, mesotrione,and control). Injury plants variables related evaluated. Although herbicideshad effect yield, be inferred that FS505 more sensitive mesotrione than FS715, since injurywas greater seen FS715. combinations selective FS505PWU (with gene). Despite injury, which pronounced hybrid, there wasno negative impact yield performance.
